METAL oLocir.

T 0 all ce hom t 'may concern Be it `known that l, CHARLES E. TTL- LTAMs7 a citizen of the United States, residing at lVinsted, county of Litchi'ield, State of Connecticut, have invented a certain new and useful Improvement in Metal Clocks7 of which the following is a full, clear, and eX- act description. l

The present invention relates to clocks and more particularly to metal alarm clocks, and has tor its object to provide novel and improved means in a cloclr ol this character 'for holding the dial glass or crystal in place. V

In the accompanying drawings- Figures l and 2 are rear and side elevations, respectively, of a metal alarmrlock embodying the features of the invention in their preferred itorm; and

Sis a vertical sectional view taken. onrltre line 3 3 of Fig. l.

ie metal alarm clock illustrated in the drawings is provided with a casing having a forward part 4- ot sheet metal in the form oiI a cylindrical shelh a back cover 6 i the forward portion of which is telescopingly received in the rear vportion ot the shell fl and is held in place by screws 7 extending` through slots in the shell and screw threaded intonthe telescoping tlange ol the bach cover, and a gong 8 extending over the coven The cloelr is further provided with a dial l0 which is supported by legs ll secured to the clocl: mechanism frame l2 which in turn is secured to the baclr cover 6 of the casing. As` illustrated the dial l0 is provided with a forwardly extending peripheral flange 14rthat lits the shell 4 of the casing; A dial glass or crystal 16 is placed over the dial with the edge of the crystal `fitting the inside of the flange A of the dial. The vcrystal 16 is curved to clear the hands of the clock and the edge only ot' the crystal rests on the dial. The forward end of the shell -L of the casing extends a distance beyond the edge of the crystal and is turned inwardly to provide an annular semi-cylindrical bead 20, whose edge forms a flange engaging the margin of the crystal to co- Specification of Letters Patent.

operate with the dial and its flange to hold the crystal in place.

It will be apparent that with this construction the curved crystal is firmly and securely held in place without use of a spac ing ring or dial mat; that themarginal portion of the crystal is well protected by the semi-cylindrical bead 20; that the hands and numbers on the dial are visible at a greater angle than is' possible where a llat crystal and spacing ring or dial mat is used; and that the crystal may be easily removed and replaced by merely loosening the screws' 7 and removing the shell a oli' the casing.

What I claim is:

V l. A clock of the class described having,

in combination, a clock case, a dial7 means passing` through the wall of said casing for holding the dial in place within said casing, a curved crystal having its edge positioned against the diah said clock casing having its :front end extended beyond the edge ot the crystal and turned inwardly to form an integral bead having its edge engaging the margin of the crystal to cooperate with the dial to hold the crystal in place.

2. A clock ot the class described having, in combination. a dial having a forwardly extending peripheral flai'lgej means tor holding the dial in place, a curved crystal having its edge positioned inside of said flange and substantially fitting the liange, and a clock casing having its liront end extending beyond the edge of the crystal and turned inwardly to forma bead having its edge engaging the margin of the crystal to cooperate with the dial to hold the crystal in place. t

8. A cloclr of the class described having, in combination, a cloclr case, a dial, means for holding the dial in place within said casing.v and a curved crystal positioned over the dial and engaged thereby1 said clock casing having an inwardly turned Flange on its forward end engaging the margin of the crystal to cooperate with the dial to hold the crystal in place. t
